Prepare

Select mkdir or delete and
identify any HDFS paths to create or delete before starting the
job.

Use delete to do file cleanup prior to job
execution. Enables Oozie to retry a job if there is a transient failure
(the job output directory must not exist prior to job start). If the
path is to a directory: delete deletes all content
recursively and then deletes the directory. mkdir
creates all missing directories in the path.
